Can I do C code to use WGM110 in standalone mode instead of BGScript?
No, only BGScript is supported for stand-alone mode.
If you want to develop in C then maybe you should look at our newest Wi-Fi modules like the WGM160P.
Is there any side-by-side comparison of the WGM110 and the WGM160? If not, could you give us a quick rundown of the differences?
You can find a table summarizing the main differences on the Wi-Fi modules page: https://www.silabs.com/products/wireless/wi-fi
If you need something more detailed please reach out to our sales or distributors in your region.
